- Built using 30 series T-slotted extrusions with parts up to 3090
- All bracket assembly
- Genuine high-quality motion system components (BOM)
- Entire motion system based on high preload MGN12H linear guide rails
- Fully belt-driven with minimal belt paths
- 9mm 2GT belt in symmetrical configuration for the Y-axis
- 6mm 2GT belts for the rest of the axis
- Independent Z stepper motors with Z Tilt capability for the X-axis
- Lightweight dual plate Carbon Fiber Bed Carriage with integrated tensioner and compatible with different bed sizes and carriage configurations
- Rigid carbon fiber bed mount
- Lightweight Polyimide flex PCB 200W Bed Heater
- Double shear shaft supports for Y and X axis steppers
- High torque LDO-42STH48-2504AC stepper motors supplied with 36V for the X and Y-axis
- Dual power supply supporting 24V and 36V power standards (easily configurable for 48V)
- Driven by the Octopus Pro 1.1 board with TMC2240 drivers
- Running Klipper firmware
- Fully featured Klipper Configuration and Slicer Profiles available
- Easily serviceable External electronic box with good airflow, and support for multiple power supplies, SSRs, RPi and large controller boards.
- Good cable management with a quick disconnect Breakout Board between the printer and ebox
- Toolhead based on the Dragon HF hotend and HF extender
- Alternate hotends supported: Dragon UHF, Ace, Mellow NF-Crazy-Volcano HF, Rapido, Goliath (User Mods)
- LDO Orbiter 2.0 direct drive extruder
- Sherpa Mini supported (User Mods)
- Dual 5015 fan setup for part cooling
- Dual AUX cooling modules based on 9733 blower fans providing 64 CFM of auxiliary cooling
- Adopts the Annex Engineering Quickdraw Probe
- Zero Y offset probe placement for no gantry twist deviation
- Full bed probe coverage
- Minimalistic printed part design focused on strength and easy printability
- Printed in ASA, providing high temperature resistance
- Easily enclosed, with the main electronic components outside of the build chamber.
- The 200 mm^2 bed configuration can be fully enclose up to the frame bounding box, with no extra space needed for the bed movement. (Dimensions)
